STEAM-ENGINE.

SPECIFICATION forming part of-Letters Patent No. 439,704, dated November 4, 1890.

` Application filed February 1I, 1889.' Serial No. 299,466. (No model.)

T all whom it may concern.'

Be it known that I, CHARLES W, VANDER- HEYDEN, a citizen of the United States, residing in Grand Haven, in the county of Ot towa, in the State of Michigan, have made eertain new and useful Improvements in Steam- Engines, of which the following is a specilication.

Figure l is a front elevation of my engine,

io partly in section, with 'front cap removed.

Fig. 2 isa vertical longitudinal section of the same, taken on line l 1 of Fig. 1. Fig. 3 is a detail elevation of valve detached. Fig. 4 is a detail plan section of the steam-chest, taken on line 3 3 of Fig. l. Fig. 5 is a detail section of the upper portion of the engine, taken on line 4 4 of Fig. 2, looking from the left. Fig. G is a detail plan section taken on line 5 5 of Fig. l. y

The object of this invention is to produce a circular cylindrical engine; and its nature consists of certain characteristics, as hereinafter shown.

A is the case wit-hin which are the opera- 2 5 tive parts of my engine.

B is a shaft passingl through the case and is the means by which power is transmitted from the engine.

C is a cam flXedly attached to the shaft B. This cam is provided with a groove D, passing around it and varying to the right and left as required to answer the purpose.

E is an interior shell fastened to the case A on one side and bearing on the collar of the disk F on opposite side. The disk F revolves with the shaft B, to which it is xedly attached, and its periphery terminates in a laterally-projectin g circular flange G, the flange and disk being one and the same piece. To this flange is attached the piston-head I-I.

I I are two circular packing-rings, one of which is beveled on one side and the other is beveled on the opposite side, andthe other sides are respectively straight and these straight sides work, against the two sides of the flange G. The beveled sides of these two flanges work against beveled surfaces in the interior shell E.

.I is the circular path in which the piston- 5o head H travels.

K is the valve made wider than the width of the piston-head, having a recess therein suiciently deep to allow the piston-head to pass, leaving a portion at each end of the valve of full size. This valve revolves on two center points or journals, one being at each end, as at L and M. The lower end M rests upon and passes through the bearing N, and the upper one L is an adjustable pivot. At the end of the lower one M is the arm O, 6o and at the free end of this arm is the pin P, which works in the slot D in cam C.

The valve K is provided with packing-rings Q Q. The upper end of this valve works in the steam-chest R and is provided with portholes S S. These port-holes S S register with corresponding port-holes W WV in the case and lead into the channel traveled by the piston-head H.

T is a steam-pipe leading to the steam- 7o boiler. This steam-pipe enters any wellknown form of a three-way cock. l

The valve K is adjusted so the recess will come directly across the travel of the pistonhead. This makes the shank X an abutment, against which the steam acts the same as an ordinary cylinder-head. rlhe valve is governed in its movements by the cam C, having the groove D, into which the pin P tits. The lever V of the three-way cock is turned to 8o admit steam through one set of port-holes, as indicated by the arrows at the right in Fig. 4. The cam is turned by the movement of the piston-head, it being connected to disk F, which is fiXedly attached to shaft B, on which 8 5 is fixedly attached cam, C. As the pistonhead approaches the valve on the opposite side the valve is turned by the groove D, pin and cam P and O, respectively, so that the recess in the valve stands at right angles to 9o the position it did before, and the piston-head passes the valve through the recess, the movement of the valve having cut olf the steam. As soon as the piston has passed the valve through the movement of the cam O, pin P, and arm O, the valve is returned to the position it was in before the last movement. As soon as the piston-head passes the other set of port-holes, the steam is exhausted through them, as indicated by the arrows on left portroo hole in Fig. Al., The port-holes S S enter and leave the steam-chest on the side. Hence they have to be curved or in substantial U shape. (See Fig. 4.) The valve K serves the double purpose of letting the steam out and in the engine and a fixed point for the steam to act against. To reverse the engine, the lever V is turned to the opposite, where it is shown in Fig. 4, which makes the other set of portholes the inlet and the others the outlet. The rings l I are adjusted by the set-screws a a. A recess is cut in the side of the case for the shank Xof the valve to retreat into While the piston-head is passing. (See Y, Fig. 6.) The pin P at end of arm O is provided with a steel roller to lessen the friction. It will be observed that the cani C and shell E are on the inside of disk F.

I claiml. The combination of a shaft, a grooved cam secured to said shaft, a rotary piston, and a cylindrical valve connected to said cam and having a recess through which the piston passes, and a part forming an abutment, substantially as described.

2. The combination of a shaft, a grooved cani secured to said shaft, a disk, as F, a shell, as E, secured to the case A, bearing upon said disk and provided with a piston, and a cylindrical valve having a recess through which the piston passes, and a part foi-min g an abutment, substantially as described.

Y 3. The combination of a shaft, a grooved cam secured to said shaft, a rotary piston, and a cylindrical valve connected to said cam, having a recess through which the piston passes, and a part forming an abutment at one end thereof, and ports for admitting and exhausting the motor fluid in the opposite end, substantially as described.
